What Mackenzie doesn't know is Valerie flew to Chicago to surprise and support her during this difficult time. "Oh, Val, I'm so happy you're here," Mackenzie says. "I can't thank you enough. You cannot imagine what this means to me."
Valerie says she had no idea what her friend of 30 years had been through. "I feel regret that I wasn't there for you as much as I could have been. I was so wrapped up in my own life," she says. "So I wasn't paying attention to [Mackenzie], my sister."
